Caliber adjustable tire puncture testing device controlled by wire

Abstract

The invention discloses a caliber adjustable tire puncture testing device controlled by a wire. One end of a valve body is connected with a valve body deck and the other end of the valve body is provided with a threaded port. The valve body is connected with a gas flow controller through the threaded port. A valve body air outlet is formed in the gas flow controller. A valve core is arranged in the valve body. A sealing ring is arranged at the front end of the valve core. The valve body deck is connected with a cylinder. An abutting rod in the cylinder is connected with the valve core. A pressure adding opening of the cylinder is connected with an air inflating pump through an electromagnetic valve and a pipeline. A flange plate is connected with the cylinder. An outer circle of a conductive ring is connected with the flange plate through bolts. An outer circle wire of the conductive ring is connected with the electromagnetic valve. An inner circle wire of the conductive ring is connected with a power source through a switch. According to the caliber adjustable tire puncture testing device controlled by the wire, one time of installation is capable of conducting a plurality of tests. Due to adoption of the method of the tests of wired control, reliability and accuracy of the tests can be guaranteed.

Description

technical field [0001] The invention relates to an automobile tire blowout test device and method, in particular to a cable-controlled tire blowout test device and method with adjustable caliber. technical background [0002] With the rapid development of my country's road traffic, especially the increase in the mileage of high-grade highways, the high-speed driving volume of automobile tires has increased significantly, and traffic accidents caused by tire blowouts have occurred frequently. According to the statistics of the Ministry of Public Security, in the major traffic accidents on highways in my country, the ratio of tire blowouts is as high as 70%, and in the United States, this ratio is as high as 80% and usually causes more serious consequences. Therefore, the tire blowout phenomenon of high-speed vehicles and the impact and countermeasures on vehicle handling stability after tire blowout are issues that relevant scholars and automobile companies must face. It is ...

AI Technical Summary

Problems solved by technology

Although the use of electric detonators can achieve tire blowouts, this method is troublesome to install. Each experiment needs to dismantle and install the tires, and reinstall the electric detonators. In addition, electric detonators are more dangerous in transportation and storage. Experimental methods will undoubtedly increase the cost of the experiment and increase the risk

More importantly, the electric detonator cannot control the burst time in different situations
